Several different sources are reporting that Skype is shutting down their "Extras" program. The program was designed to help developers release third-party applications for the VoIP service. "Developers and users will have some adjustment time, though. Skype won't certify any new submissions, but it won't yank support for existing Extras either, that is, until their certificates expire. You'll still be able to install existing Extras through the Windows desktop client, and you'll still see them featured in the Skype shop. Skype will also continue to maintain its public API. Since many Skype Extras are sold to users as premium content, the shut down also has a financial impact for profiting developers. They'll have [...] until December 11, to continue using Skype Credit. Developers will need to submit a final invoice by January 25th; after that Skype will shutter its third-party shop."
